Abstract
The invention relates to an invisible electromagnetic magnetized main shaft for a driving magnetic suspension bearing, which is composed of a magnetoconductive main shaft (1), electromagnetic magnetizing coils (2), electromagnets (3) and the like, wherein the two electromagnetic coils (2) are sheathed in the magnetoconductive main shaft (1), and the polarities of the two electromagnetic coils (2) are opposite; a magnetoconductive loop is sheathed outside the two electromagnetic coils (2); and the four electromagnets (3) are installed around the magnetoconductive main shaft (1).
Description
Affiliated technical field
The present invention relates to a kind of stealthy electromagnetism magnetization main shaft that is used for Active Magnetic Suspending Bearing, this main shaft is at a plurality of solenoids of the inner installation of magnetic conduction axon, in the solenoid outside one deck flux sleeve is arranged, and connects together with main shaft; Make main shaft after rotation, itself inhales with ACTIVE CONTROL electromagnetism iron phase from carrying magnetic, realizes the suspension of main shaft under the high speed rotating state.Belong to the magnetic levitation technology field.
Background technology
Radially ACTIVE CONTROL magnetic suspension bearing technology is that symmetry was inhaled mutually around four electromagnet of dependence carried out a magnetic conduction main shaft, realizes the magnetic suspension of main shaft.Magnetic conductor only is magnetized, and after the magnetization, just might produce suction with electromagnet.After magnetic conductor main axis rotation speed surpassed the magnetic conductor magnetizing velocity, the magnetic conductor main shaft just can not be magnetized fully, will influence and electromagnet between suction.The magnetic conductor main shaft is when high speed rotating simultaneously, and its circumferential surface and the electromagnet magnetic line of force produce movement in vertical direction, and just cutting magnetic line can produce induced field, and this induced field also can influence the magnetizing velocity of magnetic conduction main shaft and fully magnetization.Strengthen the magnetic field of electromagnet in order to keep the suspended state of main shaft this moment, and original idea is in order to improve the Suspension Control power of electromagnet to main shaft.But the electromagnetic field that strengthens can make the induced field of main shaft further increase, and also just further reduces the magnetizing velocity and the magnetization efficient of main shaft, and electromagnet is reduced the Suspension Control power of main shaft.So the whole world does not all have 100,000 rev/mins magnetic suspension motor.
Summary of the invention
Principle of the present invention is in the magnetic conduction main shaft solenoid to be installed, and makes the magnetic conduction main shaft be magnetized, magnetize by solenoid in advance, utilizes this main shaft that had magnetized then, inhales with ACTIVE CONTROL electromagnetism iron phase, the suspension after the realization electromagnet is inhaled mutually to main shaft.
After high speed rotating, thrown away disengaging by centrifugal force for fear of solenoid, we put magnetic conductive jacket in the outside of solenoid, and solenoid just is wrapped in the magnetic conductive jacket like this, just can prevent that coil is thrown out of disengaging after high speed rotating.
Description of drawings
Fig. 1 is the radial section structural map that is used for the stealthy electromagnetism magnetization main shaft of Active Magnetic Suspending Bearing of the present invention.
The present invention will be further described below in conjunction with accompanying drawing.
Among Fig. 1, magnetic conduction main shaft (1), electromagnetism magnetize coil (2), electromagnet (3) etc.; Two solenoids (2) are enclosed within magnetic conduction main shaft (1) inside, and polarity is relative; There is the magnetic conduction ring set two solenoids (2) outer ring; Four electromagnet (3) be installed in magnetic conduction main shaft (1) around.
